Creating A Crt File - Intel l2ICE User Manual

FOR NON-STANDARD HOST TERMINALS
The PICE system is designed to run on either an Intel host development system with a standard
Intel CRT or on an IBM PC/AT or PC/XT with a standard terminal. The codes expected from
the terminal or sent to the terminal are those used by standard Intel or IBM terminals.
You must configure a non-standard terminal for use with the PICE system. Do this by creating
a CRT file that contains configuration commands that change the terminal codes to those
expected by PICE software.
If your terminal is one commonly used with Intel equipment, check The AEDIT User' s Guide
(order number 121756) for the listings of some commonly used CRT configuration files.
Include the CRT configuration file when you invoke PICE software. If you name the file
I2ICE.CRT, PICE software automatically configures the terminal to its specifications. Other­
wise, you must specify the file in the invocation line. For example, the following command for
a stand-alone Series III host invokes PICE software and configures the terminal according to
the specifications in the CRT file, 1510T.CRT.
*RUN :F1;I2ICE CRT(:F2:t510T,CRT)

Creating a CRT File

Check the user's manual that comes with the terminal for the codes expected and generated by
the terminal. To create a CRT file, compare the terminal's behavior with the following PICE
software expectations:
• ASCII codes 20H through 7EH display some symbol requiring a one-column space. The
carriage return (ODH), linefeed (OAH), and backspace (08H) perform their usual
functions.
• There are cursor key output codes and CRT cursor move input codes for the cursor func­
tions down, home, left, right, and up. There are also cursor key input codes for clear
screen, clear rest of screen, and clear line.
• The home position is the upper left corner.
• The terminal accepts a blank-out code that blanks out the contents of the screen.
• The CRT has 22 to 25 lines.
• The screen scrolls. When the cursor is on the bottom line of the screen and you press
RETURN (or Enter) or the line wraps around from the right margin, the top screen line is
deleted and the screen rolls up one line.
